The joke with this glass is to empty it without spilling.
If you don't know which side of the glass to drink from, you will get the wine all over you.
There are holes in the engraved rosettes, but not in every one. There are no holes in three rosettes and you can drink from the glass there without spilling.
With Dutch engraving.
A similar fop glass is in the collection of Museum Boymans van Beuningen in Rotterdam.
This glass is in original and perfect condition.
